Well I wouldn’t say the only Korean company producing original games, some of the others did, but they were often adult themed.

Everything we have by ‘Min Corp’ seems original (game code, the art often isn’t) Yun Sung’s game code also seems to be original. F2 Systems (Cross Pang) seem like another nice developer but their games aren’t very common outside Korea. Anything using a hyperstone CPU also seems original (Eolith pre-neogeo, Limenko..)

Unico are borderline, Fancy World does seem a bit close to Tumble Pop in places, but other things like Silk Road clearly seem original.

At the bottom of the scale seem to be people like Comad (I think their only true originals are Pushman and Bouncing Balls) and Diagom who surfaced recently and don’t seem to have produced an original game either. (Simpson Junior = J. J. Squawkers, Super Panda = Penguin Bros..)

What I wouldn’t argue is that SemiCom are without doubt one of the *best* Korean manufacturers producing original games which are suitable for all audiences.
